Are there any homepage placeholder services similar to launch rock? A single field for email sign up coupled with a viral component that can be tracked?

unbounce.com?

[printerjam]

I'm using Unbounce now. But they don't have a social/viral component.

Ah, sorry -- hence the question mark. Looking at launchrock now, it looks like it offers quite a bit of additional value.
